The document provides information on Huawei's leak detection system (LDS) and intrusion detection system (IDS) solutions for oil and gas pipelines. It discusses the main safety challenges faced in pipeline operations such as theft, corrosion, leakage accidents. It then introduces 4 methods for pipeline leak detection - optical fiber temperature measurement, pressure wave detection, extended real-time transient model, and optical fiber vibration intrusion detection. The document presents case studies of Huawei's successful LDS and IDS solutions implemented for pipelines in Mexico, Nigeria, Iraq, and Tanzania, highlighting benefits such as reduced leakage losses and improved monitoring capabilities.
